The effects of acute social ostracism on subsequent snacking behavior and future body mass index in children
Authors' conclusion
This prospective study suggests that a pattern of greater snack intake in response to heightened vulnerability to the effects of ostracism may contribute to increases in child BMI scores.
Study context
- Population
- Children aged 8.5 years; males 50.4%, Chinese 58.4%
- Participants

- Outcome
- Whether stress to social exclusion predicts energy intake from a subsequent ad-libitum snack and later BMI
- Follow-up
- 6- and 18-months later
